WRENCH FOR NUT-LOCKS.

To all whom it may concern Be it known that 1, AnsAN A. FAUCHER, a citizen of the United States, residing at Milan, in the county of Marathon and State of Visconsin, have invented certain new and useful Improvements in \Vrenches for Nut-Locks. of which the following is a specification.

This invention relates to improvements in wrenches, more particularly to a special form of wrench designed to release a nut from its locking mechanism and then removing the nut, and has for one of its objects to provide a simply constructed device which eit'ectually accomplishes the desired results.

Another object of the invention is to provide a simply constructed wrench which may be employed for the specific purpose above noted and also employed as an ordinary key wrench.

WVith these and other objects in view, the invention consists in certain novel features of construction as hereafter shown and described and then pecitically pointed out-in the claim.

Figure l is a plan view of the improved wrench with the releasing lever disposed in open position. Fig. 2 is a side elevation with the head portion in section on the line 2-2 of Fig. 1, and with the releasing lever in closed position. Fig. 3 is a detached perspective view of. the releasing lever and its head.-

The improved wrench comprises a stock or handle 10 having a hollow nut engaging socket 11 at one end. The socket is provided in its upper face with a relatively large opening 12. Spaced above the socket is a plate 13 which is connected at its sides to the body of the socket leaving the ends unconnected and forming a chamber above the socket. The plate 13 is provided with an opening 14 which corresponds to and registers with the opening 12 of the socket. Mounted for rotation through the apertures 1214: is a cylindrical shell 15 having a plurality of recesses 16 in its lower edge whereby a plurality of teeth-like projections 17 are formed, the apertures 12-14 thus earner Specification of Letters Patent. Application filed September 13, 1912.

serving as bearings to support the shell 15. Arranged to swirg upon the outer face of the stock 10 is a releasing lever 18 which projects at one end into the chamber between the plate 13 and the socket 11 and is divided into coacting arms 19 which bear around the shell 15 from opposite sides and are riveted or otherwise secured to the shell as shown at :20. By this simple means the shell may be oscillated by moving the lever 18 toward or away from the stock 10. The stock 10 is provided with a stock 21 against which the lever 18 engages while in closed position to limit its movement in one direction.

The improved wrench is designed to re lease the locking pavvls ot a lock out to en-. able the nut to be removed and after the pawls are released the socket 11 is utilized to unscrew the nut and remove it from the bolt. The improved wrench may likewise s be employed to apply the nut to the bolt as will be obvious.

The specific form of nut to which the improved wrench is more particularly applicable is illustrated in an application for patent recently filed and includes a plurality of pawls between which and the bolt the portions 17: of the shell 15 are designed to engage when the lever 18 is in the posi'-' Y tion shown in Fig. 1. and then when the so lever 18 is moved over into parallel relations to the-stock 10 with the free end against the stock 21, the rotation of the shell caused by this movement will move the locking pawls outwardly and thus release them from the bolt and permit the nut to be detached, the lever 18 being held in parallel relations to the stock and against the stock 21 during the retrograde movement of the nut.

It will be noted that the shell 15 together with its teeth 17 is located within the inner end of the shell 11 leaving the lower portion unobstructed. By this'means the improved wrench may be employed as a key wrench on an ordinary nut.

Having thus described my invention, what I claim is:
